Mary (Adelaide Kane) dons a gorgeous wedding dress in this still from tonight’s (March 6) episode of Reign.

In “The Consummation,” with a forced marriage looming, Mary must consider both her heart and her nation when deciding whom she will wed – Francis (Toby Regbo) or Bash (Torrance Coombs) – when Francis returns to court with Lola (Anna Popplewell) at his side.

Further complicating matters is Mary’s mother, Marie de Guise (guest star Amy Brenneman), who visits the castle with her own agenda for Mary.

Marie’s presence worries King Henry (Alan Van Sprang) and Queen Catherine (Megan Follows), who have their own plan for the future of France, regardless of who gets hurt in the process.
